AIR-PUMP.

Patented Oct. 2, `1917.

Application rfiled November 16,1916. Serial No. 131,781. i v

To all whom/t may concern: Be it knowii that I, ANTHONY Z. MUIU- Lis, asubject of the Czar of Russia, residing at Chicago, in the county ofCookand State of Illinois, have invented certain new and usefulImprovements in Air-Pumps, of which the following is a specification.

The presentinvention relates to a mechamsm for compressing air andtransmitting 1o they air so compressed to a storage tank.

` The principal object of the invention is to usea `series of' pivotedcompressionmembers, associated with each' of which is a y weightedmember. The compression merri- -bers will be rocked by a power drivenshaft, which rocking will cause the weighted m'em bersl to slide backand forth upon a suitable mounting. rlhe weighted members are connectedto piston mechanism, and by their `back Vand forth movements will movethe pistons in and out of cylinders to effect compression of air. Thecompression members i will beso disposed about the crank shaft,

thatin ltheir movements they will act to exert a counterbalancing actionupon said shaft,y rendering more constant torque in the shaft andreducin the peak load thereof. i The invention urther consists in thefeatures of construction and combination of parts hereinafter describedand claimed.

In the drawings: n VFigure 1 is a front View of the pump of the presentinvention; y y 'y Fig. 2 across section 'showing by means H Stof fulllines the pump mechanism in one thrown position, and by means of `dottedlines the pump mechanism in neutral position; L

4 looking in the direction of the arrows.` o 1 Referring to thedrawings, the device section non line 7--7 of Fig. 4,

comprises a crank shaft 7,. which is journaled within a series oftrusses or supports 8. Attached to each oneof these crank' shafts is alink 9; and each link in turn is connected to a'plate-like supportingmem ber' 10. As shown in the drawings, there aie six ofthe connectinglinks 9, and there are six of the compressors and their supportingmembers; but since the construction and op eration' of cach is similar,a detailed ,de-y scription of only one will be entered into, althoughthe use of a plurality of these pump mechanisms is desirable in carryingout the invention, as will appear hereinafter in the description.

The pump mechanism proper includes a supporting membei' 10, heretoforereferred 70 to. This member is mounted to rock about ahollow shaft 11,which is supported by the trusses or standards 8. The supporting memberl0 is provided with upwardly eX-y` tending members 12, which receive acylinder 13j and the cylinder is secured to the f member 12, and henceto the support 10,`by means of straps` llhwhich are connected in anysuitable manner to the members 12.

Rods'15,`which as shown in the drawings 80 are two in number, lpassthrough the members 12 .with a sliding it; and the endsof these rods areconnected to the ends 16 of a weighted member 17, which member comprisesthe heavy or weighted ends 16 andthe 85 connecting portion 1S, as shown'in Fi s. 2 and 3.` Connected to each of the weig ted ends 16 is astem19, one of which is joined toa piston20, and the other of which isjoined to a piston 21, both being mounted within the interior of acylinder 13. This cylinder, centrally thereof, is formed with a web 23,in which is mounted a rotatable controlling valve 241 provided with aright-any gled port 25 and a circumferential groove 26, 95 the latterextending approximately one quarter about the circumference 'of thevalve. One end of this valve extends outbeyond' the casing; and thegroove 26 is of sufficient lengthnso that it extends into that portionof the valve lying without the casingand thereby forms a passage foradmitting outside air to the interior of the cylinder. Ati tached tothis end yof the valve is a bent finger 26 adapted to strike contacts27` and 105 28 on a valve tripping member 29,`which is .secured to oneof the rods 15 and moves back vand .forth with the shifting of theWeighted members, andV therefore'hasagrelative move ment withrespecttothe cylinders, which is necessary to operate the valve. j i

Referring now to Figs;2fa-i1d 3,,thefopetaf tion of this portion of thedevice Will be' described f Assuming that motion is imparted to thecrank? 7 and-,thc supporting member-110; with-Y the cylinder and itsassociated parts, is in-A `the position shown by means'ofth'e dottedlines in Fig.. 2, thefirstquarter revolution ofthe crank' shaftwillbring.thapartsinto the lposition shown by full linesminY Eig. 2,and"` the Weight of gravity.
